RAILROAD-GATE.

LMECIYFICATION forming part of Letters Patent No.'347,574, dated August17, 1886.

Application filed June 3, i886.

T0 all whom, it may concern Be it known thatwe, HENRY CLUEVER., of thecity and county of Albany, and State of New York, and NICHOLAS THELEN,of the city and county of Schenectady, and State of- New York, haveinvented a new and useful lmprovementjn RailroadGates, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

vFigure l is a plan view of our improved railroadgatepartly in sectionand parts being broken away. Fig. 2 isa side elevation of the same, thegate-posts being shown in section and parts being broken away. Fig. 3 isa sect-ional side elevation of the saine, taken through the linea: fr,Fig. 1.

The object of this invention is to provide railroad-gates constructed insuch a manner tliat they Wiilbe closed by the wheels of an approachingtrain and opened by the wheels of a passing train, and which shall besimple in construction, reliable in operation, and not liable to get outof order.

The invention consists in the construction and combination of variousparts ofthe railroad-gate, as will be hereinafter fully described andthen claimed.

A represents the ties, and B the rails, of a railrcadtrack.

C are shafts placed upon the opposite sides of and at suitable distancesfrom the crossing or other place where a gate is required. To the shaftsC, at the inner side of a rail, B, are rigidly attachedhorizontally-projecting arms D, upon the uppersides of which restproject-ions E, formed upon or attached to the leversF. The ends of thelevers F farthest from the gate are pivoted to supports attached to tiesA in such position that the said levers will be struck and presseddownward by the flanges of the wheels of cars approaching the gate. Thefree end s of the levers F are bent away from the rail B, so that 'theflanges of the wheels of cars leavingI the gate will pass in between therail and the said ends of the levers F, force the said levers aw ay fromthe said Serial No. 204,029. (No model.)

l rail, and pass along without operating the said levers.

The levers F are held in place at the side of the rail B by spiral orother springs, G, one end of which rests against t-he sides of the saidlevers farthest from the rail, and their other ends rest against and aresecured to supports H, attached to ties A or set in the ground.

tance from the outer sides of the rails B, are attachedhorizontally-projecting arms l, to the free ends of which are attachedthe ends of wires or chains J, which pass over guide-pulleys K, pivotedto supports attached to ties A or set in the ground. From theguidefpulleys K the wires J pass to the gate-posts L, set in the groundat a little distance from the track and at the opposite sides of thecrossing or other place to be guarded, where the said Wires J passaround guide-pulleys M,placed within and pivoted to the said posts L,and are attached to' the lower ends of vertical sliding bars N. Theposts L are formed of two parallel upright bars or plates, kept at theproper distance apart by upright bars O, interposed between and securedto the said bars or plates. Upon the adjacent sides of the interposedbars O are formed lugs P,which are perforated to receive and serve asguides for the vertical sliding bars N. The upper ends of the slidingbars N are forked, and to them are pivoted small rollers Q, which restagainst the lower sides of the pivoted gate -bars R, at a littledistance from their pivoted ends, so that the said gatebars will beraised or opened by the upward movements of the said sliding bars N.Upon the sliding bars N are placed spiral springs S, the upper ends ofwhich are attached to the said bars and their lower ends rest upon thelower lugs, P. The springs S must be of sufiicient strength to press thebars N upward with sufiicient force to raise the gate-bars R, and thusopen the gates.

Around the uppei` parts of the sliding bars N are formed annular groovesT, in such positions as to receive the inwardly-bent forked upper endsof the latches U,which are pivoted at a little distance from their lowerends to lugs V, formed upon the lower parts of the bars O. The lowerends of the latches U are bent To the ends of the shafts C, at a littledishars IC, IseI 'asI to engage iantematiealiy :witlh near thatthe said:persenziwoiild hev liable to 'the'grooves'oi'tliefsadsliding'barsassoon zheranover.:fl @pnanwwwfadowawardpnll uponthe'saidwireswillwithIl.lxfff;2:l'ldrawtiiezengagingiendsoithelsaidilateheszU,

NVith this construction, as a train of ears approaches the gate, theflanges of the enginewheels strike or press down thelever F,whieh rocksthe shaft C at that side of the gate, and causes the wires J to drawdown the sliding bars N,allowing the gate-bars Rte swing down by theirown weight, closing the gate.
